Length Optimization for Constrained Viscoelastic Layer Damping

The Journal of the Acoustical Society of America, 1970
Viscoelastic materials are used extensively to damp flexural vibrations of metallic structures; it has been known for some time that the energy dissipation due to shear strain in the viscoelastic layer can be increased by constraining it with a stiffer covering layer.

Variations on Modeling of Constrained-Layer Damping Treatments

The Shock and Vibration Digest, 1999
The de facto standard in academia for modeling constrained-layer damping (CLD) treatments revolves around the assumption that facesheets displace identically during transverse vibrations. This assumption was both mathematically convenient and appropriate for the problems addressed when it was first proposed.

Topology Optimization of Constrained Damping Layer Treatments

Adaptive Structures and Materials Systems, 2002
The aim of this research is to determine the optimal shape of a constrained viscoelastic damping layer on an elastic beam by means of topology optimization. The optimization objective is to maximize the system loss factor for the first resonance frequency of the base beam.

Constrained layer damping of tubular truss members

AIAA Journal, 1996
Summary: An efficient technique is developed to model tubular truss members with a variety of constrained layer damping treatments along its length. The truss member is divided into sections with distinct damping treatments. Each section consists of concentric layers of an outer tube, viscous layer, and inner tube.

CONSTRAINED LAYER DAMPING IN FINITE SHEARING DEFORMATIONS

Journal of Sound and Vibration, 2000
We analyze the damping induced by a homogeneous and isotropic viscoelastic layer embedded between a rigid solid cylinder of radius r 1 and a homogeneous and isotropic elastic hollow cylinder of inner and outer radii r 2 and r 3 respectively. The composite cylinder is deformed by holding the inner cylinder "xed and applying a periodic displacement K"K 0

Subproblem optimization for constrained layer damping for a panel

The Journal of the Acoustical Society of America
This work explores the use of subproblem decomposition based optimization for constrained layer damping placement and construction within a structural acoustics system. In particular, how Benders decomposition with substructuring can be used to efficiently solve a structural acoustic optimization (SAO) problem compared to traditional methods.

The Analysis and Design of Constrained Layer Damping Treatments

1980
Abstract : A tutorial work in which the mechanisms by which large shear strain may be induced in a damping layer are explored. The parameters of the system which determine the effectiveness of constrained layer treatments are identified from analyses of several geometric configurations.

Damping of Flexural Waves by a Constrained Viscoelastic Layer

The Journal of the Acoustical Society of America, 1959
For a number of years it has been known that flexural vibrations in a plate can be damped by the application of a layer of damping (viscoelastic) material that is in turn constrained by a backing layer or foil. A common example is the damping tape currently used in aircraft.
